A bicycle with 18-in.-diameter wheels has its gears set so that the chain has a 7-in. radius on the front sprocket and 3-in. radius on the rear sprocket. The cyclist pedals at 200 rpm. Find the linear speed of the bicycle in in/min (correct to at least two decimal places)
5*10^9 divided by 5*10^4
Answer:
100000
Step-by-step explanation:
5 * 10^9 = 5000000000
5 * 10^4 = 50000
5000000000 / 50000 = 100000

Write down three integers,all less than 25,whose range is 8 and mean is 11.
let
x------> the first integer
y------> the second integer
z-----> the third integer
x < y < z < 25
we know that
Median=13
Median=(x+y+z)/3
13=(x+y+z)/3
x+y+z=39------> equation 1
range=10
The range is the difference between the largest number within the set and the smallest number in the set
so
range=z-x
z-x=10------> z=x+10-----> equation 2
to find the solution we will assume different values of x (See the attached table)
terms
x < y < z < 25
z=x+10
y=39-z-x
The solution can be
7,15,17
8,13,18
9,11,19

A mailbox that is 4 1/2 feet tall casts a shadow that is 6 feet long. At the same time, a nearby ferris wheel casts a shadow 84 feet long. Find the height of the ferris wheel.
60 feet
Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.
Answer:
63 feet

8.9 – 1.4x + (–6.5x) + 3.4
Answer:
12.3-7.9x
Step-by-step explanation:
8.9+3.4=12.3
-1.4x+(-6.5x)=-7.9x
Answer:
-7.9x+12.3
Step-by-step explanation:
8.9 – 1.4x + (–6.5x) + 3.4
Combine like terms
– 1.4x + (–6.5x) + 3.4+8.9
-7.9x +12.3

Explanation
Please help me with my acellus
Answer: x = 32°
Step-by-step explanation:
(3x - 4) + (3x - 8) = 180
3x - 4 + 3x - 8 = 180
6x - 12 = 180
6x - 12 + 12 = 180 + 12
6x = 192
6x ÷ 6 = 192 ÷6
x = 32

Change this radical to an algebraic expression with fractional exponents.
Answer:
[tex] a^{\frac{1}{3} [/tex]
Step-by-step explanation:
Given, [tex] \sqrt[3]{a} [/tex].
To change this radical, we would apply the rule of fractional exponents. (i.e. [tex] a^{\frac{x}{y}} = \sqrt[y]{a^x} [/tex]
Thus:
[tex] \sqrt[3]{a} = a^{\frac{1}{3} [/tex]

Elena’s bowling league tracks the number of strikes that each player on her team gets. It also tracks the number of games bowled. The table shows the results. Name Games Strikes Elena 10 7 Jenna 7 8 Freya 3 6 Ginny 6 12 Carol 13 15 Katie 9 18 The graph shows the relationship between each player’s games and strikes. Determine which team members have the same ratio of games to strikes, and select their corresponding points on the graph.
Answer:
Step-by-step explanation:
It's asking for those who have the same amount of strikes to the amount of games. For example Jenna gas played 7 games, and Elena has gotten 7 strikes. Their asking how many members have gotten the same amount of strikes to the amount of games they've played.
This should be a big help.
